I (D '|0 E 2 l6 it; IS 54 56 D awn/m CONTAINERS FOR ELECTRICAL GLOBES RSIMILAR OBJECTS This invention relates to carton-type containers forincandescent electric light globes, or similar fragile objects and itsobject is to provide a new container of this type and a blank which maybe erected to form such a container.

A globe for which the container is particularly suitable is the typehaving a metallic base adapted to be held in the socket of a lamp orlight fitting, and a glass bulb seated in the metallic base, the bulbhaving a comparatively narrow waist adjacent the base, and an enlargedhead.

According to one aspect of the invention a blank for an electric globecarton comprises an elongated rectangular strip having a holethereinadapted to receive the metallic base of the globe, a portion of thestrip surrounding the hole being adapted to define a base for thecarton, at least two openings in the strip on either side of the baseportion, means to interconnect the two ends of the strip, and means toconnect a portion of the strip in the vicinity of each of the openingsto the base portion on opposite sides of the hole.

According to another aspect of the invention, a carton for an electricglobe comprises a base portion having a hole therein adapted to receivethe metallic base of an electric globe, and a loop portion adapted tosurround the bulb of the globe, the two ends of the loop being connectedto the base portion.

An embodiment of the invention is described below with reference to theaccompanying drawings, in which:

FIG. 1 is a plan view of a blank adapted to be erected to form a cartonto house an electric light globe;

FIG. 2 is an end elevation view of a carton-type container housing anelectric globe, the carton being formed from the blank of FIG. 1;

FIG. 3 is a side elevation view of the carton of FIG. 2, the globe andcertain fold lines being shown in chain lines; and

FIG. 4 is a semischematic end view of the carton of FIGS. 2 and 3indicating in simplified form the fold pattern of the carton, the globebeing shown in chain lines.

The blank of FIG. 1 is stamped or otherwise cut from a suitable stiffyet flexible material such as cardboard. Its outline and certain cuts inthe body of the material are indicated in solid lines; fold lines areshown in the drawing by chain lines. The blank is preferably scored orotherwise sulcated along the fold lines to facilitate erection to form acarton.

The blank comprises a substantially rectangular strip divided intovarious zones, which will now be described seriatim, starting from thetop of the drawing.

The uppermost zone in FIG. 1 is a short end zone in which are formed twoarcuate cuts 16 which define lugs 17 for interconnecting the zone 10 inthe erected carton to the other end of the strip. A circular hole 14 isalso provided in the zone 10 for purposes unconnected with thisinvention. A transverse score line 18 separates the zone 10 from arectangular zone 20 which is in the erected carton forms a verticalsidewall. The zone 20 is divided by a score line 22 from anotherrectangular zone 24 which provides the roof of the finished carton. The

zone 24 in its turn is divided by a score line 26 from a further zone 28which in the erected carton forms a sidewall opposite that provided bythe zone 20. Recesses 30 are provided in the sides of the zone 28.

Divided from the zone 30 a by a score line 32 is a zone 34, which inturn adjoins a further zone 36 and is divided from it by a score line38. An opening 40 is formed in the zones 34 and 36, straddling the line38. The opening 40 has a domelike portion 42 at one longitudinal end anda scalloped portion 44 at the opposite end. Between the portions 42 and44 there is,

on each transverse side of the opening, a lug 46 projecting inwardlyfrom the side of the strip. In the erected carton, the zone 34 forms asloping wall abutting the central portion of the globe, and the zone 36a panel through which the lower part of the globe protrudes, with theopening 40 embracing a part of the circumference of the globe in amanner to be described later.

.Below the zone 36 and divided from it by a score line 48 is arectangular zone 50 which in the finished carton forms a skirt for thebase of the carton.

The base zone or portion of the blank is provided by a zone 54 dividedfrom the skirt zone 50 by a score line 52. The base zone 54 has a hole56 formed centrally in it to receive the metallic base of the electricglobe. At its side edges it has ears 58,58, located on opposite sides ofthe hole 56 and adapted in the erected carton to receive and hold thelugs 46 described earlier. Score lines 60,60 and 62,62 define arectangular panel or space 55 within the zohe 54 surrounding the hole56, and oblique score lines 64 connect the corners of the rectangularpanel 55 to the corners of the zone 54. The corners of the rectangularpanel 55 are also connected by oblique score lines 66 to the ends of theears 58 on the sides of the strip. The lines 60,62,64 and 66 define,with the sides of the zone 54 and score lines 52 and 68, a total of foursmall triangular panels 57, two transversely elongated quadrangularpanels 59, and two longitudinally elongated quadrangular panels 61.

Below the zone 54 and divided from it by a score line 68 is arectangular zone 70 which is similar to the zone 50 described above. Ascore line 72 divides the zone 70 from a lower zone 74 which is similarto the zone 36. Finally, there are a score line 76 and a zone 78, withan opening straddling the line 76 and shaped similarly to the opening40. Towards the edge of the zone 78 semicircular holes 82 are providedto interengage with the lugs 17 formed in the zone 10 at the other endof the strip.

The openings 40 and 80 are equally spaced about the hole 56. The blankof FIG. 1 is readily folded and assembled by manual or mechanical meansto form the carton seen in FIGS. 2 and 3 and in simplified form in FIG.4.

As best seen in FIG. 4, the blank folds around the globe to form ineffect a base in which the metallic base of the globe is supported, askirt overlying the base, and a loop extending over the top of theglobe. The various zones of the blank form, in the erected carton, aroof 24, substantially upright sidewalls 20 ad and 28, sloping sidewalls34 and 78 extending from the head of the bulb towards its waist,slightly off-horizontal panels 36 and 74 embracing the waist of thebulb, lower or skirt walls 50 and 70 extending downwards along thelength of the metallic base of the globe, and apedestallike base 54comprising the panels 59 and the panel 55, which latter panel issupported horizontally and through which the base of the globeprotrudes. The ends of the strip are held together by interengagement ofthe lugs in the edge zone 10 with the semicircular holes in the zone 78.

The manner in which the ends of the looplike part of the carton,composed of the zones 34,28,24,20 and 78, are held relatively to thebase zone 54, is best seen in FIGS. 2 and 3. From these FIGS. it will benoticed that the base 54 and the various panels within it are so locatedthat the panels 59 slope upwards from the lower ends of these the skirtwalls 50 and 70 to the horizontal, centrally located panel 55. Thepanels 61, on the other hand, slope upwards from the central panel 55,with the ears 58 bent obliquely to them and with the lugs 46 extendinginto the ears and thereby holding the waist of the canon firmlytogether. The panels 57 in effect form bevel surfaces between the panels59 and 61, and serve to stiffen the base of the carton and preventdisplacement of the panels 59 and 61 from the positions determined forthem by the angular disposition of the score lines 64 and 66. The stripfrom which the carton is composed is under a slight tension whichassists in keeping the various interengaging members firmly in place.

Effective support for the globe inv the carton is provided at severalpoints. The uppermost is at the top of the globe, where the roof zone 24bears on the head of the globe. The sidewalls 28 and 28 bear on thecentral portion of the bulb at diametri cally opposite points, and thedomed surface 42 of the openings 5 40 and 80 in the sloping sidewalls 34and 78 also support the bulb where itprojects through the openings. Thescalloped edge 44 of the openings 40 and 80 in the panels 36 and 74supports the waist of the bulb a short distance above the base of theglobe. Finally, the metallic base of the globe rests in the hole 56 inthe base 54. The globe is thus prevented from moving inside the carton,or from accidentally being removed from it, the positive efi'ort ofdisengaging the locking lugs 17 in the zone 10 from the holes 82 in thezone 78 being required before the globe can be withdrawn from the gripof the surfaces 44 and the hole 56 to free it from the carton.

Erection of the carton from the blank, and insertion of the globe intoit, are simple matters that lend themselves readily to automation.

Although the invention has been described above in relation to anincandescent electric light globe, it is equally suitable for use in thepackaging of other similar fragile objects.
